Вынужденный переход на дистанционную работу в период пандемии, дал толчок активному использованию различных сервисов для общения и обучения. Одним из них стала облачная платформа для проведения онлайн видео-конференций и видео вебинаров. В некоторых случаях, попытка воспользоваться сервисом приводит к появлению ошибки 5003 в Zoom. Появляющееся сообщение, помимо кода указывает, что невозможно подключиться. При этом проблема возникает исключительно при работе через приложение.
Причины возникновения ошибки 5003 в Zoom
Такой сбой работы платформы возможен в приложении, в браузерной версии подобного кода не возникает. Причины появления ошибки могут быть следующими:
- Блокировка брандмауэром.
- Закрытие доступа антивирусной программой, который может разорвать связь с серверами Zoom.
- Подключение через прокси-сервер или VPN.
- Сбиты сетевые конфигурации.
Решать проблему доступа на облачную платформу следует исходя из причин. Иногда эту ошибку удается устранить быстро, просто перезагрузив роутер, ведущий раздачу Wi-Fi.
Обратите внимание! Код ошибки 50003 может появиться только в приложении программы, и не случается в браузерной версии.
Как исправить Zoom ошибку 5003
При сбое сетевых конфигураций выполните перезагрузку своего оборудования. Для начала отключите на пару минут роутер, и повторно его включите. Если это не помогло, примените следующие действия:
- Проверьте, не зашли ли вы через VPN, и если это так, отключите его.
- Уточните, не работаете ли у вас прокси-сервер. Его также следует деактивировать.
- Остановите на время защиту антивирусными программами, которые также могут блокировать доступ, и повторите попытку подключения к Zoom.

Why is my firewall blocking Zoom?
There have been several instances of the firewall blocking Zoom on both Windows and Mac. Here are a few reasons why it happens:
- Zoom is flagged as a threat: Whenever a program is flagged by the firewall, it’s automatically disabled from running or sharing data with the servers. And in some cases, Zoom, too, could be flagged as a threat.
- Misconfigured settings: The firewall has separate settings for programs on Private and Public networks, and it could be that Zoom is enabled on only one.
- Issues with the firewall: The firewall itself could be outdated or unreliable since programs like Zoom are never blocked. Here, we recommend you uninstall the program and switch to a more effective firewall.
How do I allow Zoom on my firewall?
You can just go ahead and open the Search function in the taskbar and look for your Windows Firewall protection settings.
Next, simply select the Allow an app through firewall option, and if you do not find Zoom on the list presented to you, you will have to add it yourself.
We explained this step with full details on solution number 5 in the guide above, so all the information you need on this topic is right there.
It’s a simple process, and it will only take up a couple of minutes of your time. So, when encountering Zoom error code 5003, the solutions above should help you fix the issue.
Share with us in the comments section below if this guide helped you through this annoying situation involving the Zoom app.
Can’t connect to your Zoom meeting with an error code 5003?
Zoom is one of the most used video conferencing applications for the past months due to the on-going situations with COVID-19.
With the large volume of users who use Zoom every day, their developers did a pretty good job in keeping their servers running and available most of the time. However, just like any other application, Zoom also suffers from occasional downtimes and errors.
One of the most common problems with Zoom is its connectivity issue like the error code 5003. There have been reports from several users who are seeing the error code 5003 every time they try to join a Zoom meeting.
The error occurs when the Zoom app fails to connect to its servers due to an overprotective firewall, a conflict with third-party applications, or a slow internet connection.
Whatever the case is, this problem should be easy to fix and you should be able to join your meeting in no time.
In this guide, we are going to show you the most effective ways on how to address the error code 5003 when joining a Zoom meeting.
Let’s get started!
- 1. Restart Zoom.
- 2. Check Zoom’s Servers.
- 3. Check Your Internet Connection.
- 4. Check Your Firewall Settings.
- 5. Disable Proxy Servers.
- 6. Disable Third-Party Antivirus.
- 7. Reinstall Network Drivers.
- 8. Run Network Troubleshooters.
1. Restart Zoom.
The easiest fix to this issue is to restart the Zoom app. Possibly, the application runs into a temporary error which makes it difficult for the app to connect to its servers. In this case, restarting the app would allow it to reload all of its resources and probably eliminate the temporary error that has occurred.
Restart Zoom on PC.
For Windows users who wish to restart the Zoom app, simply follow the steps below:
- First, press the Windows key + X on your keyboard to open the Quick Start Menu.
- After that, click on Task Manager to open it.
- Inside the Task Manager, locate the Zoom app from the list.
- Lastly, click on the Zoom app and hit the End Task button to stop the application from running.
On the other hand, for macOS users, you can restart Zoom by doing the following steps:
- On your Mac, click on the Search button at the top right corner of your screen.
- After that, type Activity Monitor and hit Enter to open it.
- Inside the Activity Monitor, locate the Zoom app.
- Lastly, click the Zoom app and hit the Stop button on the menu bar. You can either select Quit or Force Quit from the options.
Once you are done closing the Zoom app from your computer, go back to your desktop and open Zoom again. Try to join your meeting to see if the Zoom error code 5003 would still occur.
Restart Zoom on Mobile.
If you are using an Android device to join a zoom meeting, you can restart the app by performing the following steps:
- On your device, swipe up on your screen from the bottom part of the display until the app switcher appears.
- From the app switcher, locate the Zoom app.
- Lastly, flick the Zoom app upwards until it is removed from the list to stop it from running.
On the other hand, if you are using an iOS device, you can restart the Zoom app by doing the following.
For iOS devices that use an all-screen display, you can restart an app by simply swiping upwards from the bottom of your screen until the app switcher appears. After that, find the Zoom app and flick it upwards until it is gone from the app switcher.
Now, if you are using an older iOS device with a Home button, simply double-tap the Home button to open the app switcher. Locate the Zoom app and flick it upwards until it is removed from the list to stop it from running.
After closing the Zoom app on your mobile device, go back to your home screen, and tap the app to open it. Join the Zoom meeting once again to see if the error code 5003 would still occur.
2. Check Zoom’s Servers.
If Zoom’s servers are currently down, then you won’t be able to do anything on your side to fix the error code 5003 since the problem is on their side.
To verify this, visit Zoom’s official site where the status of their servers is displayed. On the site, ensure that all of its servers are operational.
Now, if their servers are indeed down, the only thing that you can do is to check their site from time to time to stay updated on the current status of their servers.
3. Check Your Internet Connection.
The next thing that you should do is to check your internet connection. Since the error code 5003 is related to connectivity problems, it is possible that your connection is not stable or too slow to perform a video call.
To verify this, you can use third-party sites like Fast.com, which accurately measures the upload and download speed of your internet connection.
If the test results come out to be slow or not close to the internet speed bandwidth indicated on your monthly subscription plan, try to restart your router. To do this, simply locate the power cable of your router and remove it. Now, wait for 5 to 10 seconds before plugging back the power cable on your router.
Once your router has started up, perform another speed test to see if your internet connection is already fixed. However, if you are still having internet connection issues, it is best that you contact your ISP (Internet Service Provider) and report to them the problem that you are experiencing with their internet service.
4. Check Your Firewall Settings.
If the Zoom app is not able to access your internet connection properly, then it would have difficulties connecting to its servers which causes the error code 5003. To ensure that Zoom can access your network connection properly, make sure that it is allowed on your Firewall.
- On your computer, press on the Windows key + S and search for Windows Defender Firewall.
- After that, click on Open.
- Inside Windows Defender Firewall, click on ‘Allow an App Through Windows Defender Firewall’.
- Lastly, locate the Zoom app from the list and make sure that it is allowed on your firewall.
Give your system a restart after applying the settings. Now, open Zoom once again and try to join a meeting to check if you are able to join it successfully.
5. Disable Proxy Servers.
Just like Windows Firewall, a proxy server acts as a security layer between your system and the internet. Your proxy server settings might be causing issues with the Zoom app and it tries to block it from accessing your network.
To fix this, temporarily disable your proxy servers while using the Zoom app:
- On your computer, press on the Windows key + I to open Windows Settings.
- After that, click on Network & Internet.
- Inside the Network Settings, click on Proxy from the side menu.
- Lastly, make sure that ‘Use a Proxy Server’ is turned off.
Now, open the Zoom app again and try to join a Zoom meeting to check if the error code 5003 would still occur.
However, if you still see the error code after disabling your proxy server, go ahead and try doing the next method below to fix the issue.
6. Disable Third-Party Antivirus.
While antivirus software is a good way to keep your system free from malware and other viruses, it is quite harsh on other programs like Zoom which it can mistakenly flag as a suspicious app and blocks any form of connection with the app.
To address this, you can try disabling any third-party antivirus software on your system if you are going to use Zoom to avoid this kind of conflict.
Alternatively, you can also remove your third-party antivirus permanently from your system and use the built-in Windows Defender which is also great in protecting your operating system.
7. Reinstall Network Drivers.
Connection issues on your computer can also be caused by a problematic network driver. If your drivers are not installed properly or corrupted, then your computer hardware like network adapters would not function properly.
To fix this, try reinstalling your network drivers to make sure that it is not corrupted.
- On your computer, press on the Windows key + S and search for Device Manager.
- Next, click on Open.
- Inside the Device Manager, click on Network Adapters to expand it.
- Lastly, right-click on your current network adapter and select Uninstall Device. Follow the on-screen prompts to proceed.
After uninstalling your network drivers, restart your computer and Windows would automatically install the best suitable driver for your network device.
Now, try to open Zoom and join your meeting to see if you can connect successfully.
8. Run Network Troubleshooter.
If you are still having problems with Zoom after performing the steps above, what you can try doing is to run the built-in network troubleshooter on Windows. It is a useful tool that can detect and fix any issues related to your network, which may cause the error code 5003 on Zoom.
To run the network troubleshooter, follow the steps below.
- On your keyboard, press on the Windows key + I to open Windows Settings.
- Inside Windows Settings, click on Update & Security.
- After that, click on Troubleshoot.
- Next, click on Internet Connections.
- Lastly, click on Run the Troubleshooter. Follow the on-screen prompts to guide you on how to use the tool.
If the troubleshooter suggested a possible solution to your network problem, simply click the ‘Apply this Fix’ button to make the changes on your system.
Once done, try to join your Zoom meeting to check if you would still encounter the error code 5003.
However, if you are still seeing the error code 5003 when joining a Zoom meeting, it is best that you contact Zoom’s technical support and report to them the issue that you are having. Be sure to give important details like your username and the device that you are using so that they can provide a solution that suits you the best.
This ends our guide on how to fix Zoom error code 5003. If you have other ideas on how to solve this issue on Zoom, kindly share it in the comment section below and we would be glad to give you credit for the solution once we update this article.
If this guide helped you, please share it. 🙂

I’m trying to set up mattermost-plugin-zoom 1.4.1 (OAuth) according to manual

That is weird. There is a bug in the code that that particular path may lead to plugin termination. Nevertheless, the path it is taking should happen only if the OAuth flow finishes with an «empty state».
The state is sent into the flow, and the same values should return when the OAuth flow is finished. No idea how this might be happening on your side.
@vmakarenko are you still seeing this? Are you seeing any other weird behaviour that may lead to this?
We tried again. Authorize plugin -> Error 500. mattermost.log:
{"level":"error","ts":1597935595.674938,"caller":"mlog/log.go:175","msg":"Invalid or missing user_id parameter in request URL.","path":"/api/v4/users/zoom","request_id":"aaa1is3bdpygfqwjjpoep7sayh","ip_addr":"188.192.118.178","user_id":"gprzfjykw7bk9fxfj57cqjgx7w","method":"GET","err_where":"Context","http_code":400,"err_details":""}

Moreover, where is the ** Enable Password based authentication** feature located? It is mentioned in https://mattermost.gitbook.io/plugin-zoom/installation/mattermost-setup and cannot be found in mattermost (5.24.2) and zoom-plugin (1.4.1) settings.
Regarding the «Enable Password based authentication», it was removed on 1.4.1. The same effect is by setting «Enable OAuth» to false.
Regarding your problem, can you confirm when you are seeing this error? Are the steps the following?
- Configure the plugin both on Zoom side and Mattermost side
- In mattermost, write
/zoom startor click on the zoom icon on the top right - Click on the link you receive to connect your account
- Introduce your Zoom credentials
- 500 error happens.
Is this the flow you are seeing?
If you want you can contact me on Mattermost Community (my username is @daniel.espino.garcia).
@larkox Hi Daniel, sorry for delay. We still need help with the problem. Let me contact you next week? Thank you already!
We see the same behavior when clicking the install button when setting up the Zoom part.
I switched on debug logging in Mattermost to retrieve some more info:
zoom_log.txt
- Zoom calls can be created with /zoom start or the button
- Authentication of a single user works
- Webhook for end of a meeting works
We still get:
2020-10-09T13:49:12.579+0200 warn mlog/sugar.go:27 Could not verify webhook secreet {«plugin_id»: «zoom»}
in our logs.
I’m not sure, if this is a real issue as everything seems to work, still the error messages are misleading/annoying.
Mattermost 5.27.0
Zoom 1.4.1
Regards
JP
@jprusch Regarding the logs, can you give me more information on how that happens? I know why the panic happens, but that state should never be reached. Do you have any «complex» backend configuration (cluster, db read replicas…)?
Regarding the second error, is there any chance you have more than one webhook configured for this app? If webhooks are working fine, but you are seeing that error, the only thing that comes to my mind is that there is another misconfigured webhook.
@larkox: I tried again with OAuth according to https://mattermost.gitbook.io/plugin-zoom/installation/zoom-configuration/zoom-setup-oauth. Same result:
http response:
invalid state
500 internal server error

It would be highly wanted to understand what went wrong.
Our setup: nginx + not dockerized instance of mattermost (5.24.0). Probably the problem is the lost HTTP headers by proxying or something similar? We can also ask for support by mattermost, we have an E10 license.
@jprusch Regarding the logs, can you give me more information on how that happens? I know why the panic happens, but that state should never be reached. Do you have any «complex» backend configuration (cluster, db read replicas…)?
Regarding the second error, is there any chance you have more than one webhook configured for this app? If webhooks are working fine, but you are seeing that error, the only thing that comes to my mind is that there is another misconfigured webhook.
Sorry for the late answer: We use a standard Mattermost standalone enterprise installation with a default MySQL backend. No clustering , no read replicas. Nginx is used as a reverse proxy with standard configuration.
@vmakarenko Thank you for your patience. Somehow I missed your message. The state should come in the oauth query string. Something like this:
https://www.yourinstance.com/plugins/zoom/oauthcomplete?code="really long gibberish"&state="shorter gibberish"
Could you check if the URL looks like that? If it is not, there might be a problem with the proxy.
@jprusch Can you also check my previous message and see if you are having a similar issue?
@larkox Back from some days off…. After restart & checking config the issue cannot be reproduced anymore. Meetings can be started from MM. Ending the meeting sends a message to the channel.
Thx.

@vmakarenko This is puzzling me. You are using v1.4.1, right? The only instance I have seen this happening is when you use the «Install» button on the Zoom website (since that button does not go through Mattermost and therefore does not set the state). If you are following the link in mattermost and not the Install button on the Zoom website, I still don’t know how this can happen.
Another thing to check is the Zoom URL you get when the oauth process start (i.e. the site where you enter your zoom credentials). That URL should also hold the state.
I’m having a similar issue. I cannot install the oauth app on the zoom site.
I receive the message «invalid OAuth user state» when I try. Starting meetings works, but I haven’t seen the webhook work.
@srpape Are you trying to hit the «install» button at the end of the Zoom setup? That is not needed.
Regarding webhooks, have you configured them on the Zoom side? Is you instance receiving the calls (maybe some info in the server logs)?
@srpape Are you still experiencing issues here?
@larkox Yes, I was hitting the «install» button at the end of the Zoom setup.
I did try to use it anyway, and we had people experiencing issues. I ended up reverting and going back to JWT after messing around with it for quite a while. I’ll give it another try at some point, but don’t hold the ticket open for me.
Great. If there is anything I can do to help you, do not hesitate to open a new bug, or contact me on Mattermost Community.
@vmakarenko Thank you for your patience. Somehow I missed your message. The state should come in the oauth query string. Something like this:
https://www.yourinstance.com/plugins/zoom/oauthcomplete?code="really long gibberish"&state="shorter gibberish"Could you check if the URL looks like that? If it is not, there might be a problem with the proxy.
I am facing the same error as being discussed «invalid OAuth user state» .
@larkox
My URL looks like this : https://chat.abc.co/plugins/zoom/oauth2/complete?code=zkXmkQSN6MDggTUFxV4QsiEcn2NuqBV3g
is there anything wrong ?
@mickmister Do you know who can help troubleshooting this?
Sure, @Kshitij-Katiyar are you or another developer able to look into this?
@mickmister Sure looking into this. Should i reopen this issue ?
@Kshitij-Katiyar I’d say let’s leave it closed unless it’s determined that there needs to be a code change here
@umairjamali Do you have any more information on how this was produced, that may be specific to your environment? I assume you ran /zoom connect to connect your account? Is the plugin configured correctly otherwise?

Therefore, in this post, we’ll show you steps for when you cannot connect to Zoom rooms and fix the Zoom error code 5003. Plus, this guide caters to whichever platform you might use, which is either Windows, Mac, Android, and iOS devices. So skim through these quick and straightforward steps and see what works best for you.
11 Fixes for the Zoom Error Code 5003 or “Unable to Connect” Error
1. Restart the Zoom Application
This should be your first go-to step to confront this issue as it’s known to solve various minor technical issues. By doing this, essentially, you’re ending the initial session with the Zoom app before reopening the app to begin a new session.
This step can prove to be effective, as in the initial session, the memory or app cache may accumulate the more you interact with the app. Most notably if you’ve tried re-entering the Zoom room multiple times just to check if that resolved the issue.
Thus, rebooting the app can clear this unnecessary built-up memory. So, you’ll have a faster user experience, free from lag interfering with your online meeting and causing connection problems.
For this, what you’ll need to do is completely close the app, wait a few seconds, before reopening it. Then, you should attempt at reconnecting with the Zoom room to check if the issue is resolved.
For Mobile (Android & iOS)
Simply exit the app by tapping the home button, then remove the app from your Recently Used Apps. After that, tap on the Zoom app, to reopen it.
For PC (Windows & macOS)
In both Windows and Macs, merely closing the application by clicking the red X button at the corner of the window won’t close the app completely. To completely close the Zoom app, for Windows PCs, from the Windows tray on the taskbar, right-click the Zoom app icon and click Exit. Following that, you can open the Zoom application.
You can also check if Zoom is completely shut down through the task manager. If Zoom is still running and appears in the task manager, right-click it, and select End Task.
For Mac Users: From the top menu bar, select the Zoom icon that is running, then from the drop-down, click Quit Zoom. After a few seconds, you can reopen the Zoom app.
2. Restart Your PC or Phone
Whether you’re on your PC, mobile device, or just about any modern tech, rebooting it is known to solve various technical issues effectively. Similar to the previous step, restarting your device can remove certain unnecessary cache, mainly system cache. Hence, significantly freeing up your RAM and speeding up your device along with its apps.
Moreover, it’s known to prevent glitches as well, so you’ll have fewer interruptions or latency during your video call.
For this, you don’t need to do any extensive reset, and a simple restart does the trick. Plus, your device should be able to do a full reset within 1 minute. So, do give this step a go, before proceeding with the rest of the steps in this guide.
For Windows: Click the Windows icon at the bottom left corner, then from the Start menu, click on the Power button, and choose Restart.
For Mac: The easiest way to prompt a restart is, click the Apple Menu, situated at the top left corner of the screen, then from the drop-down, select Restart. At the subsequent message asking “Are you sure you want to restart?”, click Restart.
For Android: Press and hold the Power button on your Android Device, then from the subsequent pop-up choose Restart.
For iPhone: The simplest way to restart is, press and hold the Power button, then slide the Power Off switch to turn off your phone. After about 1 minute, you’ll need to turn on your iPhone, so press and hold the power button till the Apple logo appears.
With that, after a quick restart of your device, your device will undoubtedly feel smoother. Thus, do open the Zoom app and check if the Zoom error code 5003 is still popping up.
3. Disable Your Antivirus and VPN
This step is mainly for PC users since it’s common for them to use third-party Antivirus or VPN software. Usually, using these software shouldn’t affect your essential apps that pose no harm to your device. In fact, using a VPN or Antivirus can ensure your device’s security during your online sessions and when browsing the net.
Nonetheless, we’ve seen reports of certain antivirus and VPN services interfering with users’ online apps such as particular games or even apps like Zoom. This may be because the services can sometimes restrict or even stop the internet connection to the apps attempting to connect online. Usually using poor-quality VPN and Antivirus software that are often offered for free can cause these connection interferences.
Therefore, we would suggest opening your VPN and Antivirus application, temporarily disabling it, then try rejoining the Zoom room. That way, if you still cannot connect to your Zoom rooms, then we can rule out your VPN or Antivirus as the cause.
Conversely, maybe consider investing in more premium antivirus and VPN options.
If you ask us, we recommend NordVPN, which is fast for our browsing needs and a daily driver, keeping us protected at all times, even during our Zoom meetings, as it leaves no interruption to our internet quality.
So, do check out NordVPN and their insanely-valued deals for a good-quality VPN subscription!

4. Disable the Firewall (FOR PC)
According to the Zoom Help Centre, Along with using particular Antivirus software, the Firewall is also a primary cause for connectivity errors with the app, mainly the Zoom Error Code 5003. This may be because if the Firewall isn’t configured correctly, it can prevent your device from receiving certain info from the online Zoom servers. Hence, this leads to latency and connection failure.
Thus, we would recommend temporarily disabling the Firewall to determine if that resolves the issue. After that, you can allow permission to the Zoom app to bypass the Firewall.
On that note, we’ll demonstrate step-by-step how you can disable the Firewall on your Windows PC or Mac.
For Windows PC: Firstly, click the Search button at the bottom left corner of the screen, then search and open Virus & threat protection. Next, select Manage Providers, and here you can view and change the Antivirus(Step 3) and Firewall settings.
To disable the Firewall, under Windows Firewall, select Open app. Since you’re using a public WiFi, click on Public network. Following that, under Windows Defender Firewall, turn the switch off, and at the next message click Yes.
Now that the Firewall is turned off, you should check if Zoom can connect again.
For Mac: Open the Apple Menu, by clicking the Apple logo at the upper left corner, then from the drop-down, choose “System Preferences…”.
Following that, select Security/Security & Privacy, and click on the Firewall tab.
Next, click on the lock icon at the bottom left corner, and input your admin username and password to allow configurations. After that, click Turn Off Firewall.
To allow the Zoom app permission to bypass the Firewall, you can click the Advanced option for further Firewall reconfigurations.
Finally, after checking the Zoom app, do remember to turn the Firewall back on, to prevent any security breach on your PC/Mac.
5. Update the Zoom Application
Keeping the Zoom app running its latest version is seen to resolve technical issues as well effectively. This is because these updates come with useful bug fixes that may prevent interfering bugs from causing connection issues.
Besides that, updating can also improve the app’s performance; hence connection losses and latency during your online session can be averted. So, if you’ve noticed the app feeling a little sluggish when navigating through it, this may mean that the app requires updating.
With that said, the following are steps to update the Zoom app on whichever device you might be on.
For Desktop app on Windows PCs and Mac
To check for updates, click on your Profile icon at the upper right corner, and from the drop-down, select Check for Updates. If you receive the “Update Available!” message, click Update to begin installation promptly.
For Android and IOS
Simply go to the Play Store(Android) or App Store(IOS), go to the Zoom app page, and if there’s an update available the Update button will be visible, so tap on it.
Better yet, you can even choose to enable auto-updates for the app.
6. Check the Status of Zoom Servers
At times, the connectivity issue may not lie on your end. In fact, it may even be due to an error at Zoom servers preventing you from connecting. Thus, you may face issues interacting with various services such as Zoom Meetings or Zoom Chat.
However, this rarely occurs thanks to their robust servers that are always up and running. Nevertheless, it’ll only take a few seconds to inspect the server status briefly.
To check this, you can visit the Zoom Service Status page by clicking here. From here, you can view the status of all their services and whether they’re operational.
Other than that, you can also visit Down Detector to view the status of Zoom services. This is also a preferable option since you can see and compare with reports from other users as well. You can click here to visit the Zoom status page on Down Detector.
7. Use an Alternative Method to Join the Zoom Room
This is another step to fix the Zoom error code 5003, that has worked for users. For instance, if initially, you joined the room by clicking a link, instead try inputting the Meeting ID and password and vice versa.
Depending on the admin, some Zoom rooms don’t allow users entering through the one-click access link, as a safety measure. Especially considering that you’re prone to zoom-bombing and other security breaches with link access.
Thus, it’s better to join the room manually. For this, open the Zoom app, Select Join, input your Meeting ID, then click Join once more, and you may be prompted to input your password as well.
Therefore it’s just as simple to join a room whichever way you choose.
8. Wait 5 minutes, then Rejoin the Zoom Room
If many people are attempting to join a particular room at the same time, this can cause some unavoidable connection problems. You’ll be stuck on the Connecting page, and eventually, you may even be prompted with the “Unable to Connect” error message.
Thus, it’s best to wait for the servers to free up, and this should only take a few minutes. Plus, this is the only step you’re left with if you find the Zoom servers to be down or overloaded from Step 6.
In that case, we would recommend, waiting a few minutes, before restarting the Zoom app and attempting to join the room.
9. Contact the Zoom Technical Support
If you’re still unable to connect to Zoom, you can bring up the issue with the Zoom Technical Support team. That way, they can point out whether there’s an issue with your account, network, or maybe even an error on their end.
If you’re a free user like most of us, the only method to contacting their support is through submitting a support ticket. Thus, it may take up to a few hours(maybe more) for them to reply.
To submit a support ticket, go to the Zoom Help Centre page by clicking here. From here, you’ll need to sign in to your Zoom account which you were using. After that, filling up the form is fairly standard, as you just need to follow the instructions under each box.
10. Check and Disable the Proxy Settings (FOR PC)
As a bonus step, we’d suggest trying this step too, mainly because it’s one of the causes for an Error 5003 as stated on the error message. Although using a proxy has its benefits to users, such as increased security and bypassing certain restrictions, it too can potentially interfere with your connectivity. Thus, apps like Zoom may face issues connecting online to their servers with restrictions from the Proxy settings.
On that note, try temporarily disabling your Proxy settings, and see whether that manages to resolve the issue. Luckily, it’s fairly straightforward to check and deactivate these proxy settings. Plus we’ve prepared steps below for you, whether you’re on a Windows PC or a Mac.
For Windows PC
Click the Search button at the bottom left corner, then search for Internet Options and open it. After that, from the top menu, choose Connections and select LAN settings. Next, uncheck the boxes under Automatic configuration and Proxy server. Once done, click OK.
For macOS
Firstly open the Apple Menu, by clicking the apple icon, then select “System Preferences…”, and choose Network.
From the list of internet connections on the left, select your WiFi network that you wish to disable the proxy settings, then click “Advanced…”. Next, choose the Proxies tab, and uncheck all the boxes under “Select a protocol to configure:”. Once you’re done with that, click OK.
11. Check Your Internet Speed
Having a weak internet connection with low speeds can also result in you being disconnected from your Zoom rooms. Therefore, you can check your internet speed using apps like Speedtest by Ookla.
Preferably, you’ll need an internet connection with around 1mbps of download and upload speed for an adequate video call experience. For a more detailed list of internet requirements, you can refer to the Zoom System Requirements page under Bandwidth requirements by clicking here.
With that, if you find your internet speeds to be unsatisfactory, worry not, as there are a few minor ways for you to improve your internet speeds temporarily. Firstly, you should consider restarting your internet router which can cool down your router. Plus, this clears the built-up memory in the router that can potentially slow down the connection.
Besides that, you should also consider positioning your device in closer proximity to your internet router during online zoom meetings. This is to prevent your WiFi signals from being blocked by wireless connections and large solid objects like walls. Hence, this can increase the connection strength, and you’ll undoubtedly see a bump in your internet speeds.
If going on multiple video calls are a crucial part of your job description, consider investing in an upgraded internet plan. You can also try contacting your ISP if you aren’t receiving the speeds you’re paying for.
Conclusion
In a nutshell, nobody wants to be late to their Zoom meetings and keep their coworkers, friends, or worse their BOSS waiting. It’s like being late to a regular meeting, and that can make you look unprofessional.
With that, say goodbye to last-minute scramblings through Google and tech forums on workarounds to this connectivity issue. We’ve curated the steps you can take to fix when you’re unable to connect to Zoom or the Zoom error code 5003.
